Here are 10 interesting facts about their decades-long marriage.

10 They Separated But Will Never Divorce

In 2012 the much loved couple announced their separation, only to be reconciled the following year. However, they split once more later that year. Despite their decision to separate, Rhea said that the couple will never get divorced.

Rhea explained her rationale in an interview with the NY Post: "We agree on enough things, so why [ruin] that with the yucky things that come with a divorce?"

Both theater veterans, it was during a 1971 production of The Shrinking Bride that Rhea and Danny met. The latter had been acting in the play and caught Rhea's eye.

At the time, the NY Times gave the production a favorable review, praising DeVito's "zany performance" in particular, so perhaps it was this zaniness that attracted Rhea.

Speaking of the theater, both Rhea and Danny were involved in the Westbeth Playwrights Feminist Collective, a woman-run theater group that was active from 1971-1975. These days, Danny is most famous for his role as the vulgar Frank Reynolds in the long-running It's Always Sunny in Philadelphia, so his involvement in a feminist theater group shows a different side to him.

In 1972, he and Rhea acted together in one of the collective's productions, Up - An Uppity Revue.

Before becoming a huge star, Danny was part of the main cast of one of the most acclaimed sitcoms of all time, Taxi. His character, Louie, was selfish and obnoxious and his long-suffering girlfriend, Zena, was played by none other than Rhea Perlman.

Zena wasn't part of the main cast of characters, though she did appear in 7 episodes.

6 They Made Sure Their Kids Celebrated Both Their Religions

The couple has 3 children together: daughters Lucy and Grace, and son Jacob. Rhea is Jewish, while Danny is Catholic. Subsequently, the couple decided not to favor one faith, but to ensure their kids got to celebrate both religions.

As Rhea told the Los Angeles Times, "We do all the holidays to keep the traditions and the culture going, but I truly don't have a great feeling about any particular organized religion, and I don't think it's right to impose one on my kids."

5 Their Daughter Made A Controversial Appearance In 'It's Always Sunny In Philadelphia'

Lucy DeVito is the couple's eldest child. At 38, she is all grown up now and she had a blink-and-you'll-miss-it cameo in the Always Sunny episode "Dennis and Dee Get a New Dad". But her appearance was far from wholesome.

In fact, she plays a waitress that Danny's Frank Reynolds ogles. To make the scene even more uncomfortable, Frank's date says, "Isn't having children a blessing?" as he leers at the waitress. Yikes. Only Always Sunny could get away with a joke this uncomfortable.

4 When Filming 'Matilda', They Cared For A Grieving Mara Wilson

One of the saddest behind the scenes facts about the much loved 1996 movie Matilda, which DeVito directed, is that star Mara Wilson's mother, Suzie Shapiro, was gravely ill with cancer during filming. Subsequently, Danny and Rhea, who play her parents in the movie, looked after the 9-year-old when her mom was in the hospital.

In a truly moving gesture, Danny even ensured that Mara's dying mom got to see the finished movie before she passed. He visited Suzie in the hospital and took a copy of the movie so that she could watch her young daughter's magical performance. She died before it hit cinema screens and the movie was dedicated to her memory.

3 They Share The Same Political Views

Danny has always been a staunch Bernie Sanders supporter and it appears as though Rhea shares the same views. As she said in a Watch What Happens interview, "We really agree on almost everything important." Rhea's name also appears on a Bernie Sanders donor list.

2 Danny Has Praised Rhea's Acting Skills

Sometimes there can be rivalry within acting couples. Thankfully, this is not the case for Danny and Rhea. When queried about their separation, Danny praised his wife's acting talents, telling People, "She's a good actress and I love working with her." It's important that they can still appreciate each other despite their break up.

1 They Remain Great Friends Despite Their Separation

It's not common for former partners to remain amicable following a break up. Remaining friends is even rarer. But for Danny and Rhea, their friendship is forever. As Rhea explained to Andy Cohen, "I don't know why it's difficult for other people, but Danny and I have always loved each other and we have three amazing children together."

Meanwhile Danny told People, "We're friends. We're happy. Everybody's happy."
